Post kiam mi lavas miajn manojn, mi sekigas ilin per pura tuko.

Post kiam means after or more literally after when. It introduces an action that happens earlier than the main action.

So in this sentence:

• Post kiam mi lavas miajn manojn = After I wash my hands
• mi sekigas ilin per pura tuko = I dry them with a clean towel

If you used only kiam, the meaning would be closer to when, which is less specific. Post kiam clearly shows that the drying happens after the washing.

In Esperanto, -as is the present tense. It can be used for:

• actions happening now
• habitual actions
• general routines

Here, the sentence sounds like a general routine: After I wash my hands, I dry them with a clean towel.

So lavas and sekigas do not necessarily mean this is happening at this exact moment. They can describe what the speaker generally does.

If you wanted a past version, you would say:

• Post kiam mi lavis miajn manojn, mi sekigis ilin...

If you wanted a future version:

• Post kiam mi lavos miajn manojn, mi sekigos ilin...

Because miajn manojn is the direct object of lavas.

Breakdown:

• mano = hand
• manoj = hands
• manojn = hands as a direct object
• miajn = my, agreeing with manojn

In Esperanto:

• -j marks plural
• -n marks the accusative, usually the direct object

So:

• miaj manoj = my hands
• miajn manojn = my hands (as the thing being washed)

Since I wash my hands, hands receives the action, so it takes -n.

Adjectives and possessive words in Esperanto agree with the noun they describe.

Since manojn is:

• plural → -j
• accusative → -n

the possessive miaj must match it:

• miaj manoj
• miajn manojn

This agreement is a very regular feature of Esperanto.

Ilin means them, and it refers back to miajn manojn.

Since hands is plural, the pronoun must also be plural:

• ili = they
• ilin = them

And it has -n because it is the direct object of sekigas.

So:

• mi sekigas ilin = I dry them

You could repeat it, but ilin sounds more natural because Esperanto, like English, often uses a pronoun to avoid repetition.

Compare:

• mi sekigas miajn manojn = I dry my hands
• mi sekigas ilin = I dry them

Both are possible here, but ilin is smoother because miajn manojn was just mentioned.

This is an important point.

• seka = dry
• sekiĝi = to become dry, to get dry
• sekigi = to make something dry, to dry something

So sekigas literally means make dry.

That matches English dry in a transitive sense:

• I dry my hands = Mi sekigas miajn manojn / ilin

If you said mi sekas, that would suggest I am dry or something related to being dry, not I dry something.

Esperanto often distinguishes clearly between:

• something becoming a certain way: -iĝi
• making something a certain way: -igi

Per means by means of, with, or using.

So:

• per pura tuko = with a clean towel

It shows the instrument used to do the action.

Other examples:

• Mi skribas per plumo. = I write with a pen.
• Li malfermis la pordon per ŝlosilo. = He opened the door with a key.

Because per pura tuko is not the direct object. It is a prepositional phrase introduced by per.

In Esperanto, prepositions like per, kun, en, sur, etc. normally do not take the accusative just because they are in the sentence. The noun after the preposition stays in its normal form unless there is some special reason to use -n.

So:

• pura tuko = a clean towel
• per pura tuko = with a clean towel

The direct object in the main clause is ilin, not tuko.

The comma separates the introductory subordinate clause from the main clause.

• Post kiam mi lavas miajn manojn = subordinate clause
• mi sekigas ilin per pura tuko = main clause

Using a comma here is normal and helps readability.

Yes. Esperanto word order is fairly flexible, although some orders sound more neutral than others.

The given sentence is very natural:

• Post kiam mi lavas miajn manojn, mi sekigas ilin per pura tuko.

You could also say:

• Mi sekigas ilin per pura tuko post kiam mi lavas miajn manojn.

That is still understandable, but the original version is probably the most straightforward because it presents the earlier action first.

Esperanto often uses possessives with body parts when that is the clearest and most natural choice.

So miajn manojn is completely normal.

In some contexts, Esperanto can use la manojn when ownership is obvious, but miajn manojn is very clear and beginner-friendly:

• Mi lavas miajn manojn. = I wash my hands.

For a learner, using the possessive here is a safe and natural choice.

Tuko is a cloth, piece of fabric, or towel-like cloth depending on context. In this sentence, because it is used to dry washed hands, pura tuko is naturally understood as a clean towel or a clean cloth.

So the exact English word may vary slightly by context, but towel is a very natural translation here.
